I'm reminded of something (Noam Chomsky?) once did, where he spoke at (Harvard?) and began listing atrocities (it wasn't true) committed by Arabs against Jewish people in Israel/Palestine and the people were absolutely aghast at what they heard, utterly horrified, and then....revealed that actually it was the other way around, that it was the zionists who'd committed those atrocities against the Palestinian population, and he said he noted with some interest that the room breathed a sigh of relief
